W opracowaniu dokonano porównania wybranych wskaźników ekonomicznych w gospodarstwach według siły ekonomicznej (ESU) w 2007 roku. W zakresie analizy wykorzystano poziom kosztów i wysokość dopłat w przeliczeniu na jednostkę siły ekonomicznej (ESU). W zakresie kosztów występuje tendencja wyraźnego podziału na kraje nowo przyjęte i państwa UE- IS, zaś w zakresie wsparcia - dopłaty maleją wraz ze wzrostem siły ekonomicznej gospodarstw.
The member states of the European Union differ. They have different natural environments, various economic conditions as well as differing farm structures. The aim of this paper is to evaluate the input efficiency in generating economic value of production. To realize the aim the cost/economic size ratio and subsidies/economic size ratio were analyzed across EU countries. The analysis also included a short assessment of differentiation potential of agriculture. The study covered the year 2007. The potential of agriculture in EU countries is considerable different. The observed level of productive potential of agriculture is strongly correlated with the level of costs and the amount of support obtained. The differences of support level came from historical entitlements of current CAR support scheme. If the costs per economic size unit are taking into consideration there are two cluster observed. In EU-12 (new members) considerable higher costs are recorded then in EU-15 (old member states). It was also observed that there were significant differences in variation of the cost per economic size unit in separate farm groups with different economic size. The difference rose with increasing of economic size of the farms and differences between particular EU countries in cost variation were bigger in large farms. The subsidy/ economic size ratio average in the EU decreasing with increasing economic size of the farms, and additionally the highest level of this ratio was observed on the north EU countries, and decrease with moving to the south.
